Available in PDF, EPUB and Kindle. Book excerpt: This book contains the successful submissions to a Special Issue of Energies entitled “Engineering Fluid Dynamics 2019–2020”. The topic of engineering fluid dynamics includes both experimental and computational studies. Of special interest were submissions from the fields of mechanical, chemical, marine, safety, and energy engineering. We welcomed original research articles and review articles. After one-and-a-half years, 59 papers were submitted and 31 were accepted for publication. The average processing time was about 41 days. The authors had the following geographical distribution: China (15); Korea (7); Japan (3); Norway (2); Sweden (2); Vietnam (2); Australia (1); Denmark (1); Germany (1); Mexico (1); Poland (1); Saudi Arabia (1); USA (1); Serbia (1). Papers covered a wide range of topics including analysis of free-surface waves, bridge girders, gear boxes, hills, radiation heat transfer, spillways, turbulent flames, pipe flow, open channels, jets, combustion chambers, welding, sprinkler, slug flow, turbines, thermoelectric power generation, airfoils, bed formation, fires in tunnels, shell-and-tube heat exchangers, and pumps.

Download or read book Experimental Study of Two-dimensional Turbulent Wall Jet Development with and Without Longitudinal Free Stream Pressure Gradient written by Douglas Howard Neale and published by . This book was released on 1971 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of various wall jet flows was conducted. The major areas of investigation were: The wall jet injected into still air; The wall jet under a constant-pressure main-stream flow; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a substantially thickened initial boundary layer; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a thickened and distorted initial boundary layer. Detailed velocity profile and local skin friction measurements were made at numerous streamwise distances from the jet slot. For the case in which no main-stream flow was present, the studies were carried out for a wide range of slot Reynolds numbers. For the wall jets with main-stream flow, selected ratios of free-stream velocity to jet velocity at the jet slot were investigated. The growth of characteristic thickness and decay of jet peak velocity is presented for all wall jet studies. Also, velocity and temperature profile similarity is described. Skin friction laws are shown for the constant-pressure wall jets and a single 'law of the wall' valid for all wall jet studies is set forth. Finally, the skin friction and velocity profile measurements are presented in tabular form. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In a novel application of the temporal numerical simulation, an investigation ofturbulence modeling techniques is carried for the turbulent wall jet over aconvex surface (Coanda wall jet.) The simultaneous presence of multipleinstability mechanisms and the interaction with the turbulence dynamics at thesolid boundary produces a unique combination of different large turbulentcoherent structures that constitutes both a consistent challenge for numericalsimulations and an ideal test bed for turbulence models. The Temporal Direct Numerical Simulation (TDNS) of the Coanda wall jetrestricts the focus from the global turbulent Coanda wall jet to a smaller, localportion of the flow and offers a wide array of advantages to the present work. Inparticular, the size of the computational domain can be arbitrarily chosen inboth the spanwise and the streamwise directions. This allows to either suppressor enhance individual physical mechanisms and, consequently, to selectivelyreproduce different large coherent structures within the local flow. In the firstpart, temporal numerical simulations are employed to reproduce four differentflow scenarios of the local Coanda wall jet with a level of numerical resolutionthat, because of the reduced size of the computational domain, cannot be matchedby standard DNS of the entire physical flow (spatial DNS, or SDNS.)The TDNS of these four flow scenarios are then used in the second part for ana--posteriori analysis of different turbulence models in order to addresscommon shortcomings shown by Hybrid Turbulence Models (HTM). For each flowscenario, the turbulent flow field is deliberately decomposed in resolved andunresolved flows by the application of different filters in space correspondingto different grid resolution. The behavior of turbulence models can be reproducedfrom the resolved flow and compared to theturbulent stress tensor directlycalculated from the unresolved part of the flow field. Starting from the RANSlimit, turbulence models with different levels of complexity are studied. Successively, the performance of these models is analyzed at intermediatenumerical resolutions between RANS, LES, and DNS. Finally, an improvedformulation of the Flow Simulation Methodology (FSM) is proposed.

Download or read book A Computational Model for Three-Dimensional Incompressible Small Cross Flow Wall Jets written by Norman D. Malmuth and published by . This book was released on 1977 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational model based on H. Keller's box scheme has been used to characterize turbulent incompressible wall jets in the small cross flow approximation prototypic of flows over upper-surface-blown and augmenter wings. Submerged and coflowing cases are considered. An eddy viscosity model was used to simulate the effects of turbulence. Approximate models are identified for flows in which the jet height tends to zero. If the span flow is introduced through a lateral curvature term appearing in the spanwise momentum equation, the effect of the turbulent coupling on the surface pressures, and peak spanwise velocities is weak. (Author).
